Nextflix has acquired streaming rights to Hush, the micro-budget horror thriller written and directed by Mike Flanagan and starring his co-writer Kate Siegel. Blumhouse’s Jason Blum and Intrepid’s Trevor Macy produced the pic, which had buyers circling when WME arranged a first screening last fall in Toronto. It bows at SXSW on Sunday and will debut on the streaming service beginning April 8.

The plot: After losing her hearing as a teenager, author Maddie Young (Siegel) has lived a life of isolation fully retreating into her now silent world. When the masked face of a psychotic killer appears in the window of her secluded home, she must push herself beyond her mental and physical limits in order to survive the night. John Gallagher Jr., Michael Trucco and Samantha Sloyan also star. Michael J. Fourticq Sr., Jeanette Brill, Kate Lumpkin and Couper Samuelson are exec producers.

The trio of Flanagan, Intrepid and Blumhouse first teamed on Flanagan’s Oculus, which was the biggest-grossing film acquired at the 2013 Toronto fest.
